Thank you very much Robert.I have been using SuSE10.0 that contained
twisted.I could not find twisted when updating to SuSE10.1Wired.I am
back to suse10.0 again.I will learn more about twisted from now.<br><br><div><span class="gmail_quote">On 12/7/06, <b class="gmail_sendername"><a href="mailto:twisted-python-request@twistedmatrix.com">twisted-python-request@twistedmatrix.com

<br>compiler) installed. Parts of Zope Interface (and Twisted, too) are<br>written in C, so one is needed. Most Linux distributions install one<br>automatically, but as far as I know some don't if you don't ask it<br>to install development software. Either that, or it's installed but
<br>not in your PATH.<br><br>Anyhow, there should be a GUI program for adding/removing programs,<br>so use it to install "gcc". If not, and you are using Ubuntu or<br>Debian "apt-get install gcc" or for Fedora try "yum install gcc" and
<br>then try building Twisted again.<br><br>Please excuse me if you know all this already (you are building<br>Twisted after all). It just seems like problem is that GCC is not<br>installed/cannot be found.<br><br>Robert<br>
